To all whom it may concern:

. Be it known that we, LEWIS M. Rnnnn and DAVID S. GOULD, citizens of the United States, residing at Kent, in the county of lliing and State of Washington, have invented new and useful Improvements in Coolers or Refrigerators, of which the following is a specification.

This invention relates to a cooler or re- Lt'rigerator for domestic and other uses, the object of the invention being to provide a cooler which is adapted to be arranged in the line of a water service pipe within a house or other building, so that in the circulation of the water through the pipes, when water is drawn from the faucets, the

frigerator will maintain alow temperature therein "for the preservation of contained perishable sub-stances.

it further object of the invention is to provide a cooler or refrigerator which is simple of construction, inexpensive of installation and use, which provides for the cooling action of the water in an eficient manner, which provides also for free ventilation of the interior compartments containing the substances to be cooled, and which dispenses with the necessity of employing ice as a refrigerant or cooling me- The invention consists of the features of construction, combination and arrangement oi parts hereinafter fully described and claimed, reference being bad to the accompanying drawing in which ll ignre 1 is a front elevation oi a cooler or reh'igerator embodying our invention, and showing the same arranged between sections of a water conducting pipe.

Fig. 2 is a vertical longitudinal section through the device.

Fig. 3 is a sectional 3-4) of Fig. 1.

ln carrying our invention into practice we provide a cooler or refrigerator comprising a preferably cylindrical outer casing 1, which is vertically disposed and pro vided with top and bottom head portions 2 and 3 constructed and arranged to form a water tight receptacle. Arranged within cold water passing through the cooler or replan view on the line this outer casing 1 is a similarly shaped, but

smaller, inner cylindrical casin 4 provided with top and bottom heads 5 an 6 also constructed and applied to form a water tight receptacle. The two receptacles are concentrically arran ed and the inner receptacle is spaced at all sides from the outer receptacle tn provide a water containing jacket or chamber 7.

The casing 1 is arranged between sections 8 and 9 of a water service pipe of a house or other building leading from the main to discharge faucets, and is provided with inlet and outlet connections 10 and 11 communieating with the said pipesections 8 and 9, respectively. The inlet connection 10 is located at one side of the casing l, in proximity to the bottom thereof, while the outer connection 11 is arranged at the diametrically opposite side of said. casing and adjacent to the top thereof, so that the cold water entering said casing will flow first into the bottom of the chamber 7 and upwardly to the top of said chamber before discharge. The outlet 11 is arranged substantially at the level 0:? the discharge pipe section 9, so that in the use of the device it will be understood that thewater chamber or jacket 7 will at all times be filled with a cool body of water up to the level of the outlet 11, thus keepin the inner casing 4, which will be entirely surrounded by said body oi water, at a low temperature.

The casing 4 is provided with a series of shelves, trays or other suitable supports 12 on which the substances to be kept cool, or dishes or other receptacles containing the same, may be placed, and at its front the casing 4: is provided with a doorway or opening 13 which registers with a doorway or opening letin the front of the outer casing 1, a flange or partition 15 extending between the margins of said doorways or open ings, forming a water tight connection whereby the doorways are separated from the water space, allowin free and ready access to the interior of t e inner casing at all times. For the purpose of securing'free ventilation of cold air within the inner casing, said casing is provided at its lower end with an air inlet pipe or tube 16 and at its upper end with an air outlet or exhaust tube or pipe 17, whereby the interior of the inner casing will at all times be kept dry and provision made for carrying ofi' all odors from the food or other substances contained therein.

In the use of the device, it will be understood that it may be arranged within a kitchen or pantry of a house, or in a stutable portion of a store, in the line of con ill nection between sections oil a cold water supply pipe leadin to faucets trend which water is periodica y drawn, by means oil which the cooling etlect oi? the water will be utilized for a regerating action without cost in this connection, the circulation ot the water causing a constant chang oitthe body of water within the cooler by means oi which the heat contained within the inner casing will be abstracted and carried ofi, thus maintaining said inner casing at a low temperature at all times. By the construction described a simple,,inexpensive and economical type of refrigerator or cooler is provided for household or other use, which entirely dispenses with the use of ice, and which in many casesmay be employed in place of the ordinary refrigerator.

We claim A device of the class-described, comprising an outer casing, an inner casing spaced from the outer casing in a vertical direction, said space forming a water jaclret that partially surrounds the inner casing, inlet and outlet pipes to permit water to circulate in the yiaclret and abstract heat from the interior and contents oi the inner casing, a tubular spacing element between the. upper walls of the two casings and another element between the bottom walls, opegs in each of the walls of the casing to register with the openings in the tubular spacing cl ents said elements serving as a ventilating means to provide for changes of air within the inner casing, an opening having a door giving access to the inner casing, and means surrounding the opening and between the two casings to prevent the water from leaving the jacket except at its proper outlet,

in testimony whereof we afix our signatures in presence of two witnesses.
